Abstract
With rising the environmental issues regarding the fossil fuels, the renewable energy resources (RES) could be as interesting scheme in supply side for micro grids. The aim of this paper is to investigate the feasibility of photovoltaic (PV) system in Iran both in grid-connected and island mode. The case study is a residential house in the city of Amol. The software of HOMER (Hybrid Optimization of Multiple Energy Resources) is used for analyzing the data for finding the optimal design among the various solutions which takes in to account electrical and economic assessment factors. In the section of grid-connection mode, two different simulation methods namely HOMER optimizer mode and optimal sizing design mode is used to better understand the grid participation with PV in supplying the power for load demand. Finally, the optimal and affordable design for selected region is grid-connected PV system which alleviate the energy need from grid.
Highlights
These days, due to the global warming and environmental issues of using fossil fuels, RES can play dominant role for supplying the energy demand in the world
The simulation analysis for PV system has been done on grid-connected mode
Island mode which has based on HOMER optimizer for finding the optimal sensitivity amounts of the equipment has been investigated in the second scenario. 4.1 Grid-connected mode
Summary
These days, due to the global warming and environmental issues of using fossil fuels, RES can play dominant role for supplying the energy demand in the world. Lior [1] investigated that with this amount of energy consumption in the world, the fossil fuels resources will be ended at the end of this century. The aim of this study is to investigate the feasibility of using and developing the PV system as source of RE for providing the sustainable and reliable electricity supplies for residential load in Iran. Samimi [3] studied the potential of solar irradiation in Iran and reached that this country possesses desirable condition in using solar energy. Supplying the load demand from PV system could be beneficial solution for alleviating the dependency to the fossil fuels [4]. The HOMER is one of those software’s which is used by RE planners to obtain ideal system among the different feasibility study solutions [5]
